The Schold Vacuum Drum Mixer is a great solution for customers who prefer to mix their product directly in the shipping container. A drum or bucket is secured on a steel platform using a mounting bracket and tightening strap. The vacuum bell can then be lowered and vacuum applied. Two sight glasses provide visual access to the product during the process and an electric vacuum switch monitors the level of vacuum applied. A semi-automatic control panel can automate the vacuum and mixing process through easy to set timers. A single start/stop button runs the entire process.
